Hello fellow gear heads, I have a Briggs 17 horse twin II L head, model 42a707, type 2238e1 code 003235a. Short story: I rebuilt fuel pump only to have gas shooting out the top of the carb, flooding the engine. I rebuilt the carb and cleaned it although she was pretty clean. I rebuilt the fuel pump and checked it twice, still major gas comming out top 2 holes of carb. I know I have put it together correct per the manual, and I have quite a bit of experience with these. They are fairly simple What am I missing??????????????? I replaced fuel and vacuum hoses, cleaned everything. What do you think?
